Kumho Ecsta PS71 vs Pirelli Powergy — Compared

“Kumho PS71 Question Replaced an older (2021 or 2022 production) set of ps71 with a new set (production 39-42 week of 2024) and noticed something on the new sidewalls I hadn't seen on the old ones. The new ones have ps71 with either a 1 or a 2 under it right above the bead in very small text. I'm curious what they mean if anything at all.”

“go with Kumho Ecsta PS71 EV around £140 – £165. Good value for money”

“Those are Kumho Ecsta PS71s, thread width is supposed to be 245mm, the actual one is hardly 235. How so?”

“Ripples in side wall Just been washing the car and found what I can only describe as ripples in the side wall of my front-right tyre. Had these fitted in June, only just noticed the ripples. The other tyres are perfect. I’ve probably done around 2,000 miles on them. Should I be concerned, and do they look like a manufacturing defect, or as a result of damage? (I’ve not hit any serious potholes that I’m aware of). These tyres are Pirelli Powergy, fitted to a Volvo XC60. Date code is 3325. Any help gratefully received. Read more”

“Are Pirelli Powergy Winter the right winter tires for the GR? Hey, my parents bought a GR Yaris last week and it’s a great car but I looked at its winter tires and those are Pirelli Powergy Winter. I’m not an expert on tires but as far as I know the P-Zero Winter would be the right choice for a GR. My father didn’t bought them because he thought it was the right tires rather a tire salesman talked him into it. I talked him into Pirelli as those were the factory tires for his Volvo 850R and would be a better choice then his current Conti Premium 5 but somehow my father misunderstood me to that point that Pirelli’s are the greatest tires ever. So he asked the salesmen for the best Pirelli Tires and told the car it’s for but the salesman sold him those Powergy tires and said that not all Pirelli’s are in stock. As my father isn’t an enthusiast but loves likes to drive performance cars he didn’t knew better and now it’s too late. In my eyes a good salesman (not in the way of profit for the company rather costumer experience) would have told him that the P-Zeros winter are out of stock but can be ordered or would show him tires from different companies. Another option is the salesman though he meant the GR Sport Yaris for which P-Zero winters are too much as not many persons in their sixties drive a real GR. So my question are the Powergy enough for the GR or should he get P-Zeros next Winter (in a few weeks we will put on summer tires)”

“Pirelli cinturato P7 and Pirelli Powergy Hi all 👋🏼 So I had 4 Pirelli Cinturato P7’s on my Ford Focus ST. I got a flat tire (front left) while I was on vacation so I decided to get 2 new tires at the front. I asked the guy at the tire shop to get the same tires (so the Pirelli Cinturato’s). He got me Pirelli Powergy’s instead… He didn’t really speak English and there was not time as I was driving home the next day. So I just accepted it. Now my question is what’s the main difference between these tires? And does it matter I got 2 different tires now? (2 powergy’s at the front and 2 Cinturato’s at the back) Thanks!🙏🏼”
